Abstract

Disclosed is a method for determining filter coefficients. The method includes: obtaining the coefficients of a target filter and calculating the response of the target filter; computing according to collected data and/or predetermined data in accordance with a first data pattern so as to have the response of a first filter approximate to the response of the target filter and thereby determine the coefficients of the first filter; and computing according to the collected data and/or the predetermined data in accordance with a second data pattern so as to have the response of a second filter approximate to the response of the target filter and thereby determine the coefficients of the second filter. Accordingly, the difference between the responses of the first filter and the second filter is insignificant and results in less negative influence; and the first and the second filters can replace the target filter to reduce cost.

A method for determining filter coefficients, comprising:

obtaining coefficients of a target filter and thereby calculating a target filter response, in which the target filter response relates to a way of the target filter to process original data;
computing according to collected data and/or predetermined data in accordance with a first data pattern so as to have a difference between a first filter response and the target filter response be less than a threshold and thereby determine coefficients of a first filter, in which the first filter response relates to a way of the first filter to process first data originated from the original data;
and
computing according to the collected data and/or the predetermined data in accordance with a second data pattern so as to have a difference between a second filter response and the target filter response be less than the threshold and thereby determine coefficients of a second filter, in which the second filter response relates to a way of the second filter to process second data originated from the original data.
